Web handlers provide a way to easily add additional _routes_ to your [Web Server](./web-server.md).

> :information_source: Keep in mind that the SSL certificate provided by Let's Encrypt's Certbot is by default stored in a privileged location; if your ENIGMA instance is not running as root (which it should not be!), you'll need to copy the SSL certificate somewhere else in order for ENIGMA to use it.
## Static Routes
Static files live relative to the `contentServers.web.staticRoot` path which defaults to `enigma-bbs/www`. This is also commonly known as your "public root".
## Static Root
Static files live relative to the `contentServers.web.staticRoot` path which defaults to `enigma-bbs/www`. This is also commonly known as your "public root" directory.
## Custom Error Pages
Customized error pages can be created for [HTTP error codes](https://en.wikipedia.org/wiki/List_of_HTTP_status_codes#4xx_Client_Error) by providing a `<error_code>.html` file in the *static routes* area. For example: `404.html`.
## Web Handlers
[Web Handlers](./web-handlers.md) are loaded by the web content server and provide a easy way for adding additional routes & functionality to ENiGMA.

title: WebFinger Handler
---
The WebFinger ([webfinger.js](/core/servers/content/web_handlers/webfinger.js)) [Handler](./web-handlers.md) provides basic [WebFinger](https://webfinger.net/) ([RFC7033](https://www.rfc-editor.org/rfc/rfc7033)) support, enabling servers such as those participating in the [Mastodon](https://en.wikipedia.org/wiki/Mastodon_(social_network)) [Fediverse](https://en.wikipedia.org/wiki/Fediverse) to discover basic information about a user.
# Supported Features
* [profile-page](https://webfinger.net/rel/profile-page/)
* [ActivityStream URI](https://www.w3.org/TR/activitystreams-core/) via rel of `self` and of type `application/activity+json`
* Subscription URI template via rel of `http://ostatus.org/schema/1.0/subscribe`
# Configuration
By default, the WebFinger handler is not enabled. To enable, at a minimum set `contentServers.web.handlers.webFinger.enabled` to `true` in `config.hjson`:
```js
contentServers: {
web: {
handlers: {
webFinger: {
enabled: true // wow, much nest!
}
}
}
}
```
## Configuration Keys
| Key | Description |
| ----|-------------|
| `enabled` | Boolean. Set to `true` to enable WebFinger services |
| `profileTemplate` | String. Provide a fully qualified, or relative to [static root](./web-server.md#static-root) path to a template file for fetching profile information. See [Profile Template](#profile-template) for more information.
## Profile Template
A profile template file can offer flexibility as to what information, the format, and MIME type served by the [profile-page](https://webfinger.net/rel/profile-page/) WebFinger query. Set the `profileTemplate` key in your `webFinger` configuration block to a path to serve as the template. The MIME type will be determined by the file's extension:
```js
contentServers: {
web: {
handlers: {
webFinger: {
enabled: true
profileTemplate: './wf/fancy-profile.html'
}
}
}
}
```
> :information_source: A sample template can be found at `www/wf/profile.template.html`
